Overview

Childhood obesity is a Body Mass Index (BMI) at or above the 95th percentile for children of the same gender and age. It is a serious health problem that can result in health complications. Childhood obesity can be caused by lifestyle factors, underlying medical conditions, genetic causes or certain medications. It is important to differentiate obesity due to lifestyle factors from obesity due to medications or an underlying medical condition. Obesity in general may present with high blood pressure, insulin resistance, excess facial hair or irregular menstruation. The presence of polyuria and polydipsia suggests possible diabetes, excess facial hair, insulin resistance and irregular menstruation in adolescent girls may be due to polycystic ovary syndrome (PCOS) and dry skin, constipation and intolerance to cold suggest hypothyroidism. laboratory tests indicated depend on the clinical presentation. Management of obesity includes the treatment of any underlying medical conditions and lifestyle modification.

Historical Perspective

  • In 450 B.C., the first Obesity was developed as a medical disorder by the ancient Greeks .[1]
  • In 550 B.C., obesity was linked to heart disease and diabetes by the Indian surgeon Shushruta.[2]

Classification

Pathophysiology

  • The pathogenesis of childhood obesity is characterized by energy imbalance
  • This energy imbalance is the result of excess energy intake and/ or decreased energy expenditure.
  • It has been suggested that a dysfunction in the ghrelin/leptin hormonal pathway may contribute to abnormal appetite control and increased energy intake.

Causes

Childhood obesity may be caused by unhealthy dietary intake, unhealthy lifestyle, environmental factors, psychological factors,genetic causes, an underlying medical condition, medications or hypothalamic obesity.

Dietary intake

Children and adolescents are consuming low nutrient high-calorie foods and beverages at home, school and other places. They are consuming more fast food which is low in nutrients and high in calories, fat and sodium. CDC reports that children and adolescents in the U.S. consumed an average of 13.8% of their daily calories from fast food during 2015-2018. [3] In addition, they are consuming large amounts of sugar-sweetened beverages which has been directly associated with obesity in multiple reviews.[4] [5]

Lifestyle factors

Physical inactivity, excess use of screen time and inadequate sleep also contribute to the obesity epidemic.[6][7] Eating habits of the child are also affected by demographics, lunch policies at schools and work demands on parents.[8]

Psychological factors

Many children eat in response to stress and or negative emotions such as boredom, anger, sadness, anxiety or depression.

Genetic factors

Often, a child whose parents are overweight or obese will also be overweight or obese. Although this is often caused by shared unhealthy eating habits in the household, it has been suggested that there may be a genetic (inherited) predisposition toward being obese, although this is as yet unproven and research is ongoing.

Medical conditions

There are genetic syndromes and hormonal disorders that may be associated with weight gain and obesity in children including: hypothyroidism, cushing syndrome, growth hormone deficiency, growth hormone resistance, leptin deficiency or resistance to leptin action, polycystic ovary syndrome (PCOS), precocious puberty, prolactin-secreting tumors, turner syndrome, down syndrome, cohen syndrome, prader-Willi syndrome, pseudohypoparthyroidism and laurence-moon-biedl syndrome.[9]

Medications

Medications that may cause weight gain in children include cortisol and other glucocorticoids, tricyclic antidepressants, sulfonylureas, monoamine oxidase inhibitors, risperidone, clozapine, oral contraceptives, insulin (in excessive doses) and thiazolidinediones. [10]

Hypothalamic obesity

Weight gain may occur after acquired hypothalamic lesions following surgery, cranial radiation or diencepahlic tumors. It can also be a result of cranial trauma or inflammation of the hypothalamus. [11]

Differentiating childhood obesity due to lifestyle factors from other Diseases

Epidemiology and demographics

  • The prevalence of children who are overweight or obese worldwide is approximately 38 million in children under the age of 5 in 2019 and more than 340 million between 5 and 19 years old in 2016.[12]
  • In 2015-2016, the prevalence of Childhood Obesity among children aged 2-19 years was estimated to be 13.7 million cases (18.5%) in USA.[13]

Age

  • Children of all age groups may develop Childhood Obesity.
  • Childhood Obesity is more commonly observed among children aged 12 to 19 years old in the USA. This is followed by children aged 6 to 11 years old and then children aged 2 to 5 years of age.

Gender

  • Childhood Obesity prevalence by gender is different depending on the region.
  • Males are more commonly affected than females 5 to 19 years of age in most high and upper middle-income countries.[14]

Race

  • Obesity prevalence was higher among Hispanics and non-Hispanic blacks than non-Hispanic whites and non-Hispanic Asians.[15]

Risk Factors

Natural History, Complications and Prognosis

Diagnosis

Diagnostic Criteria

  • The diagnosis of childhood obesity is made when the calculated Body Mass Index (BMI) is at or above the 95th percentile on the BMI-for-age growth chart.

History and Symptoms

Physical Examination

  • Physical examination may be remarkable for:

Laboratory Findings

Treatment

Medical therapy

  • Management of obesity in children focuses on reducing BMI of the child safely, preventing and managing complications.
  • The mainstay of therapy for obesity in children is diet and exercise.
  • Setmelanotide, a melanocortin-4-receptor agonist was approved by the U.S. Food and Drug Administration (FDA) for children age 6 and older with obesity caused by rare genetic disorders.[25]

Surgery

  • Bariatric surgery are performed in some adolescents with severe obesity.[26]
